Definitions
- the present invention relates to a charging cable for an electrically-driven vehicle for use in charging a battery of an electrically-driven vehicle such as, for example, an electric vehicle or a hybrid vehicle.
- the charging facility for home use is required for the popularization of the electrically-driven vehicles and, hence, standard homes, offices and the like have started introducing a slow charging facility that utilizes a commercially available 100V- or 200V-power source.
- a charging cable for an electrically-driven vehicle for connecting a receptacle outlet of the commercially available power source and a connector of the electrically-driven vehicle is used to charge a battery of the electrically-driven vehicle.

- the power plug is inserted into a receptacle outlet provided on, for example, an outer wall of a house.
- this charging cable has the potential for causing abnormal heat generation due to incomplete connection or arc tracking between the receptacle outlet and the power plug. Because of this, a charging cable having a temperature sensor for detecting the temperature of the power plug has been proposed, wherein if the temperature sensor detects that the temperature of the power plug has exceeded a predetermined temperature, a control signal is sent to a switching circuit for opening and closing an electric circuit between the power plug and the charging coupler so that power supply from the power plug to the connector of the electrically-driven vehicle may be halted (see, for example, Patent Document 1).
- an earth leakage detecting portion for detecting an earth leakage is provided in addition to the temperature sensor for detecting the temperature of the power plug, and if the earth leakage detecting portion detects an earth leakage, power supply from the power plug to the connector of the electrically-driven vehicle is halted.

- DE102009034886 discloses a charging cable for use in charging a battery of an electrically-driven vehicle, comprising a first connector adapted to be connected to a charging station, a second connector adapted to be connected to the vehicle and a connecting cable for connecting the first and second connectors.
- the second connector comprises a temperature detector and an evaluation circuit generating a pilot signal that is sent to the vehicle in order to control the charging current.
- US4061956 discloses a system comprising a battery and a battery charger, provided with two temperature detectors respectively located in the charger itself and in the battery.
- the present invention is intended to improve the situation.
- the present invention is directed to a charging cable as defined in claim 1.
- the charging current to the built-in battery is controlled based on the pilot signal sent from the controller.
- the charging current to the electrically-driven vehicle is variably set depending on the temperature of the power plug, the controller or the charging coupler of the charging cable, the charging of the battery can be continued with a reduced charging current when the temperature of, for example, the power plug, the controller or the charging coupler increases. This feature can reduce the charging time and enhance the durability of, for example, relays, as compared with the conventional on/off control.
- the controller can easily determine failures such as disconnection of the temperature detector provided in the power plug or the charging coupler by comparing outputs from the two temperature detector with each other, thereby making it possible to enhance the reliability of the equipment.

- a first temperature detector is provided in the power plug and/or the charging coupler and a second temperature detector is provided in the controller.
- the controller can determine failures of the temperature detector provided in the power plug or the charging coupler based on outputs from the two temperature detector, thus leading to the reliability of the equipment.
- the controller sends a pilot signal that has been changed in waveform to the electrically-driven vehicle to notify the electrically-driven vehicle to reduce the charging current, thereby making it possible to prevent overheating of the power plug and enhance the safety.

- the electric circuit may be finally blocked.
- Fig. 1 depicts a state where a battery of an electrically-driven vehicle C is electrically charged from a commercially available power source of a standard home B using a charging cable A for an electrically-driven vehicle according to the present invention.
- the electrically-driven vehicle C is provided with a drive motor 2, an inverter 4, a battery 6 and a charge control device 8, all electrically connected to one another.
- the electrically-driven vehicle C is connected to the charging cable A for the electrically-driven vehicle (hereinafter referred to simply as the "charging cable") via a connector 10 connected to the charge control device 8.
- the charging cable A is used to connect a receptacle outlet 12 provided on, for example, an outer wall of the standard home B to the connector 10 on the side of the electrically-driven vehicle C to charge the battery 6 installed in the electrically-driven vehicle C.
- the receptacle outlet 12 is an outlet or socket having a waterproof structure to prevent a short circuit of electrodes due to, for example, rainwater.
- the receptacle outlet 12 is connected to a commercially available power source (not shown) for supplying a single-phase two-wire alternating-current 100V.
- the charging cable A is provided with a power plug 14 to be detachably connected to the receptacle outlet 12, a charging coupler 16 to be connected to the connector 10 of the electrically-driven vehicle C to supply electric power, a connecting cable 18 for connecting the power plug 14 and the charging coupler 16, and a charging device 20 located midway in the connecting cable 18 and having a controller (for example, microcomputer) 20a.
- a controller for example, microcomputer
- the power plug 14 has a temperature sensor (for example, resistance temperature detector) 14a embedded therein as a temperature detector for detecting the temperature of the power plug 14.
- a temperature signal outputted from the temperature sensor 14a is inputted to the controller 20a of the charging device 20.
- the charging device 20 is further provided with a switching circuit (for example, a relay or relays not shown) for opening and closing an electric circuit between the power plug 14 and the charging coupler 16 and an earth leakage detecting portion (not shown) for monitoring an electric current flowing through the electric circuit to detect an earth leakage. If the earth leakage detecting portion detects the earth leakage, the controller 20a blocks the electric circuit via the switching circuit to halt power supply from the commercially available power source to the electrically-driven vehicle C.
- a switching circuit for example, a relay or relays not shown
- an earth leakage detecting portion for monitoring an electric current flowing through the electric circuit to detect an earth leakage. If the earth leakage detecting portion detects the earth leakage, the controller 20a blocks the electric circuit via the switching circuit to halt power supply from the commercially available power source to the electrically-driven vehicle C.
- a charge control forming a core of the present invention is explained hereinafter with reference to Figs. 2 and 3 .
- Fig. 2 is a schematic block diagram of the charging cable A and Fig. 3 depicts waveform diagrams of pilot signals outputted from the charging device 20 to the charging coupler 16.
- the temperature sensor 14a embedded in the power plug 14 detects the temperature of the power plug 14 and outputs a temperature signal indicating the temperature of the power plug 14 to the controller 20a provided in the charging device 20.
- the controller 20a Upon receipt of the temperature signal, the controller 20a outputs a pilot signal corresponding to the temperature signal to the charge control device 8 of the electrically-driven vehicle C via the charging coupler 16.
- the pilot signal outputted from the controller 20a has a close relationship with a charging current. Because of this, when the charge control device 8 of the electrically-driven vehicle C receives the pilot signal indicating the charging current, the charge control device 8 can recognize the charging current that can be supplied from the receptacle outlet 12 via the charging cable A and conducts charging while controlling a supply current to the battery 6 in response to the pilot signal. The electric power charged to the battery 6 is supplied to the drive motor 2 via the inverter 4, thus enabling the electrically-driven vehicle C to run.
- Fig. 3 depicts waveforms of pilot signals outputted from the controller 20a to the electrically-driven vehicle C, (a) indicating a reference waveform, (b) indicating a waveform when the temperature of the power plug 14 is low, and (c) indicating a waveform when the temperature of the power plug 14 is high.
- pilot signals are further explained in detail taking a case where a commercially available 100V-power source is used and the power plug 14 has a rated current of 15A.
- the charging current (energization current) is set to, for example, 12A.
- the pilot signal indicating this charging current has the reference waveform shown in Fig. 3(a) and a duty ratio (D) thereof is set to 20% (pulse width: 20%, pulse interval: 80%).
- the duty ratio of the pilot signal indicates the charging current itself. If the duty ratio exceeds 20%, the charging current exceeds 12A, and if the duty ratio becomes smaller than 20%, the charging current becomes smaller than 12A.
- the power plug 14 is normally made of plastic, and assuming that the heatproof temperature thereof is 65°C, the charging cable A according to the present invention has a threshold value (for example, 50°C) set to be lower than the heatproof temperature.
- a threshold value for example, 50°C
- the duty ratio is increased (D>20%) to increase the charging current, as shown in Fig. 3(b) .
- the duty ratio is reduced (D ⁇ 20%) to reduce the charging current, as shown in Fig. 3(c) .
- the duty ratio of the pilot signal and the charging current are compliant with SAE J1772 (SAE: Society of Automotive Engineers) and have, for example, the following relationship:
- step S2 the power plug 14 of the charging cable A is connected to the receptacle outlet 12 and the charging coupler 16 of the charging cable A is connected to the connector 10 of the electrically-driven vehicle C, followed by step S3, at which the temperature of the power plug 14 is detected by the temperature sensor 14a accommodated in the power plug 14 and a temperature signal from the temperature sensor 14a is inputted to the controller 20a of the charging device 20.
- the controller 20a compares the temperature inputted from the temperature sensor 14a with the threshold value referred to above.
- the temperature of the power plug 14 is equal to an outdoor air temperature.
- the temperature of the power plug 14 increases gradually.
- the program advances to step S5, at which a control for steplessly increasing the duty ratio of the pilot signal is conducted to steplessly increase the charging current.
- step S4 if the temperature detected by the temperature sensor 14a exceeds the threshold value, the program advances to step S6, at which a control for steplessly reducing the duty ratio of the pilot signal is conducted to steplessly reduce the charging current.
- the duty ratio of the pilot signal has a close relationship with the charging current and if the temperature of the power plug 14 is low, the charging current is increased. In contrast, if the temperature of the power plug 14 is high, the charging current is reduced. This eliminates the need for the charging current to be on/off controlled, unlike the conventional way, thus making it possible to achieve a balance between a reduction in charging time and the safety of the charging cable A.
- step S6 After the charging current control has been conducted at step S5 or step S6, if the charge control device 8 of the electrically-driven vehicle C determines at step S7 that the battery 6 of the electrically-driven vehicle C has not been completely charged, the program returns to Step S3. On the other hand, if the charge control device 8 determines that the battery 6 of the electrically-driven vehicle C has been completely charged, the charge control device 8 of the electrically-driven vehicle C inputs a signal indicating completion of the charging to the controller 20a of the charging cable A, thereby terminating the charging of the battery 6.
- the controller 20a sets a maximum value of the charging current (energization current) depending on the duty ratio (pulse width) of the pilot signal outputted to the electrically-driven vehicle C and that the charging current supplied to the battery 6 of the electrically-driven vehicle C is finally determined by the charge control device 8 of the electrically-driven vehicle C.
- the charging current has been described as being changed by changing the pulse width of the pilot signal outputted from the controller 20a
- the charging current may be changed by changing a pulse waveform (for example, a pulse amplitude (level)) other than the pulse width.
- the charging current has been described as being steplessly increased or reduced by steplessly increasing or reducing the duty ratio of the pilot signal, the charging current may be increased or reduced in a stepwise fashion by increasing or reducing the duty ratio of the pilot signal in a stepwise fashion.
- the charging current is steplessly increased or reduced by steplessly increasing or reducing the duty ratio of the pilot signal
- the charging current may be only reduced in a stepwise fashion by reducing the duty ratio of the pilot signal in a stepwise fashion.
- any other alternating-current voltage for example, alternating-current 200V
- any other alternating-current voltage for example, alternating-current 200V
- a second threshold value greater than the aforementioned threshold value may be set in the controller 20a and, in this case, if the controller 20a detects a temperature greater than the second threshold value, the electric circuit is blocked.
- Figs. 5 and 6 depict a second example.
- Fig. 5 is a schematic view depicting a state where a battery of an electrically-driven vehicle is electrically charged using a charging cable according to the second example
- Fig. 6 is a schematic block diagram of the charging cable shown in Fig. 5 .
- a temperature sensor 16a is provided in the charging coupler 16.
- the temperature sensor 16a detects the temperature of the charging coupler 16 and outputs a temperature signal indicating the temperature of the charging coupler 16 to the controller 20a of the charging device 20.
- the controller 20a Upon receipt of the temperature signal, the controller 20a outputs a pilot signal corresponding to the temperature signal to the charge control device 8 of the electrically-driven vehicle C via the charging coupler 16.
- the charge control device 8 can recognize, based on the pilot signal received, the charging current that can be supplied from the receptacle outlet 12 via the charging cable A and conducts charging while controlling a supply current to the battery 6 in response to the pilot signal.
- This configuration can produce similar effects as in the first embodiment referred to above if abnormal heat generation occurs due to incomplete connection or arc tracking between the charging coupler 16 and the connector 10 of the electrically-driven vehicle C.
- Fig. 7 is a schematic block diagram of a charging cable according to a third example which is not part of the claimed subject matter, in which a temperature sensor 20b is provided in the controller 20a of the charging device 20. It is assumed that the charging of the electrically-driven vehicle C is conducted under various circumstances and that the controller 20a abnormally generates heat, for example, with the charging device 20 left in the hot sun. It is also assumed that abnormal heat generation may occur due to incomplete connection or arc tracking at, for example, connecting portions between the connecting cable 18 of the controller 20a and terminals. In the third example, the temperature sensor 20a provided in the controller 20 can prevent abnormal heat generation in the controller 20a, thus making it possible to produce similar effects as in the above-described first embodiment.
- Fig. 8 depicts a schematic block diagram of a charging cable according to an embodiment of the present invention, in which a first temperature sensor 14a is provided in the power plug 14 and a second temperature sensor 20b is provided in the controller 20a. It is assumed that a user may handle the power plug 14 and the charging coupler 16 in a rough way. Because of this, if the temperature sensor 14a is provided in the power plug 14 or the charging coupler 16, it is conceivable that the temperature sensor deteriorates in durability. In the configuration according to this embodiment, the controller 20a compares a value of the first temperature sensor 14a provided in the power plug 14 and that of the second temperature sensor 20b provided in the charging device 20 with each other to thereby easily detect disconnection of the temperature sensor 14a provided in the power plug 14.
- the charging plug 14, the charging coupler 16 and the charging device 20 may be provided with respective temperature sensors.
- the charging cable according to the present invention can reduce the charging time and enhance the durability of, for example, relays and the reliability of the equipment, it is effectively utilized as a cable for charging a drive battery of a vehicle that runs with at least the drive battery installed.

Description
- The present invention relates to a charging cable for an electrically-driven vehicle for use in charging a battery of an electrically-driven vehicle such as, for example, an electric vehicle or a hybrid vehicle.
- In recent years, electrically-driven vehicles are being developed as environmentally-friendly automobiles at a rapid pace. Charging infrastructures for the electrically-driven vehicles are largely classified into a charging facility for home use that utilizes a household power source at the end of a power network and another charging facility for public use that is available to the general public and provided in an urban area, beneath a road surface or the like.
- Also, in view of convenience, the charging facility for home use is required for the popularization of the electrically-driven vehicles and, hence, standard homes, offices and the like have started introducing a slow charging facility that utilizes a commercially available 100V- or 200V-power source.
- In the case of the charging facility for home use, a charging cable for an electrically-driven vehicle for connecting a receptacle outlet of the commercially available power source and a connector of the electrically-driven vehicle is used to charge a battery of the electrically-driven vehicle.
- This charging cable is provided with a power plug to be connected to the receptacle outlet of the commercially available power source and a charging coupler to be connected to the connector of the electrically-driven vehicle. When the battery is charged, the power plug is inserted into a receptacle outlet provided on, for example, an outer wall of a house.
- However, this charging cable has the potential for causing abnormal heat generation due to incomplete connection or arc tracking between the receptacle outlet and the power plug. Because of this, a charging cable having a temperature sensor for detecting the temperature of the power plug has been proposed, wherein if the temperature sensor detects that the temperature of the power plug has exceeded a predetermined temperature, a control signal is sent to a switching circuit for opening and closing an electric circuit between the power plug and the charging coupler so that power supply from the power plug to the connector of the electrically-driven vehicle may be halted (see, for example, Patent Document 1).
- In the case of this charging cable, an earth leakage detecting portion for detecting an earth leakage is provided in addition to the temperature sensor for detecting the temperature of the power plug, and if the earth leakage detecting portion detects an earth leakage, power supply from the power plug to the connector of the electrically-driven vehicle is halted.
- Patent Document 1:
JP 2010-110055 A -
DE102009034886 discloses a charging cable for use in charging a battery of an electrically-driven vehicle, comprising a first connector adapted to be connected to a charging station, a second connector adapted to be connected to the vehicle and a connecting cable for connecting the first and second connectors. The second connector comprises a temperature detector and an evaluation circuit generating a pilot signal that is sent to the vehicle in order to control the charging current. -
US4061956 discloses a system comprising a battery and a battery charger, provided with two temperature detectors respectively located in the charger itself and in the battery. - The present invention is intended to improve the situation.
- In accomplishing the above objective, the present invention is directed to a charging cable as defined in
claim 1. - In the electrically-driven vehicle, the charging current to the built-in battery is controlled based on the pilot signal sent from the controller. According to the present invention, because the charging current to the electrically-driven vehicle is variably set depending on the temperature of the power plug, the controller or the charging coupler of the charging cable, the charging of the battery can be continued with a reduced charging current when the temperature of, for example, the power plug, the controller or the charging coupler increases. This feature can reduce the charging time and enhance the durability of, for example, relays, as compared with the conventional on/off control.
- Also, because a first temperature detector is provided in the power plug and/or the charging coupler and a second temperature detector is provided in the controller, the controller can easily determine failures such as disconnection of the temperature detector provided in the power plug or the charging coupler by comparing outputs from the two temperature detector with each other, thereby making it possible to enhance the reliability of the equipment.
- The above aspects and features of the present invention will become apparent from the following description of preferred embodiments thereof with reference to the accompanying drawings, in which:

Fig. 7 is a schematic block diagram of a charging cable according to a third example which is not part of the claimed subject matter; and -
Fig. 8 is a schematic block diagram of a charging cable according to an embodiment of the present invention. - The present invention is directed to a charging cable for an electrically-driven vehicle for use in charging a battery of the electrically-driven vehicle, which charging cable includes a power plug to be detachably connected to a receptacle outlet of a commercially available power source, a charging coupler to be detachably connected to the electrically-driven vehicle, a temperature detector for detecting, when the battery of the electrically-driven vehicle is charged from the receptacle outlet, a temperature of an electric circuit between the power plug and the charging coupler, and a controller for generating a pilot signal indicating a charging current to the battery based on the temperature detected by the temperature detector to send the pilot signal to the electrically-driven vehicle.
- Abnormal heat generation occurs due to incomplete connection or arc tracking at a connecting portion between the receptacle outlet and the power plug, a connecting portion between the charging coupler and a connector of the electrically-driven vehicle, connecting portions between feeder cables and terminals in the controller, or the like. Accordingly, the temperature detector is provided in the vicinity of each of such connecting portions in an electric circuit in which abnormal heat generation may occur.
- As is well known, in the electrically-driven vehicle, the charging current to the built-in battery is controlled based on the pilot signal sent from the controller. According to this configuration, when the temperature detector detects abnormal heat generation, the charging current can be variably set on the side of the electrically-driven vehicle depending on the temperature detected by the temperature detector. Accordingly, for example, if the temperature of the power plug becomes high, the charging current is reduced to continue the charging of the battery while restraining a temperature increase of the power plug, thereby making it possible to reduce the charging time and, at the same time, enhance the durability of, for example, relays.
- Also, a first temperature detector is provided in the power plug and/or the charging coupler and a second temperature detector is provided in the controller. By doing so, the controller can determine failures of the temperature detector provided in the power plug or the charging coupler based on outputs from the two temperature detector, thus leading to the reliability of the equipment.
- More specifically, when the temperature detected by the temperature detector reaches a predetermined threshold value, the controller sends a pilot signal that has been changed in waveform to the electrically-driven vehicle to notify the electrically-driven vehicle to reduce the charging current, thereby making it possible to prevent overheating of the power plug and enhance the safety.
- Also, when the temperature detected by the temperature detector reaches the predetermined threshold value, the controller sends a pilot signal that has been changed in pulse width to the electrically-driven vehicle to notify the electrically-driven vehicle to reduce the charging current. In this case also, similar effects can be obtained.
- The controller may notify the electrically-driven vehicle to reduce the charging current in a stepwise fashion using the pilot signal.
- Further, when the temperature detected by the temperature detector reaches the predetermined threshold value, the controller may send a pilot signal that has been changed in amplitude to the electrically-driven vehicle to notify the electrically-driven vehicle to reduce the charging current.
- In addition, the controller may operate the temperature detected by the temperature detector to send a pilot signal that has been gradually changed in amplitude beforehand to the electrically-driven vehicle to notify the electrically-driven vehicle to reduce the charging current so that the threshold value may not be reached.
- Further, in addition to each control method referred to above, the electric circuit may be finally blocked.
- Illustrative examples and an embodiment of the present invention are described hereinafter with reference to the drawings, but the present invention is not limited by the embodiments.
-
Fig. 1 depicts a state where a battery of an electrically-driven vehicle C is electrically charged from a commercially available power source of a standard home B using a charging cable A for an electrically-driven vehicle according to the present invention. - As shown in
Fig. 1 , the electrically-driven vehicle C is provided with adrive motor 2, an inverter 4, abattery 6 and acharge control device 8, all electrically connected to one another. The electrically-driven vehicle C is connected to the charging cable A for the electrically-driven vehicle (hereinafter referred to simply as the "charging cable") via aconnector 10 connected to thecharge control device 8. The charging cable A is used to connect areceptacle outlet 12 provided on, for example, an outer wall of the standard home B to theconnector 10 on the side of the electrically-driven vehicle C to charge thebattery 6 installed in the electrically-driven vehicle C. - The
receptacle outlet 12 is an outlet or socket having a waterproof structure to prevent a short circuit of electrodes due to, for example, rainwater. Thereceptacle outlet 12 is connected to a commercially available power source (not shown) for supplying a single-phase two-wire alternating-current 100V. - On the other hand, the charging cable A is provided with a
power plug 14 to be detachably connected to thereceptacle outlet 12, acharging coupler 16 to be connected to theconnector 10 of the electrically-driven vehicle C to supply electric power, a connectingcable 18 for connecting thepower plug 14 and thecharging coupler 16, and acharging device 20 located midway in the connectingcable 18 and having a controller (for example, microcomputer) 20a. - The
power plug 14 has a temperature sensor (for example, resistance temperature detector) 14a embedded therein as a temperature detector for detecting the temperature of thepower plug 14. A temperature signal outputted from thetemperature sensor 14a is inputted to thecontroller 20a of thecharging device 20. - The
charging device 20 is further provided with a switching circuit (for example, a relay or relays not shown) for opening and closing an electric circuit between thepower plug 14 and thecharging coupler 16 and an earth leakage detecting portion (not shown) for monitoring an electric current flowing through the electric circuit to detect an earth leakage. If the earth leakage detecting portion detects the earth leakage, thecontroller 20a blocks the electric circuit via the switching circuit to halt power supply from the commercially available power source to the electrically-driven vehicle C. - In the charging system for the electrically-driven vehicle of the above-described construction, when the
power plug 14 is connected to thereceptacle outlet 12, electric power from the commercially available power source is supplied to thecharging device 20 of the charging cable A. Because the switching circuit is initially in an on-state, the electric power from the commercially available power source is supplied to thecharging coupler 16. As such, when thecharging coupler 16 is connected to theconnector 10 of the electrically-driven vehicle C, thebattery 6 is electrically charged via thecharge control device 8. - A charge control forming a core of the present invention is explained hereinafter with reference to
Figs. 2 and3 . -
Fig. 2 is a schematic block diagram of the charging cable A andFig. 3 depicts waveform diagrams of pilot signals outputted from the chargingdevice 20 to the chargingcoupler 16. - As shown in
Fig. 2 , thetemperature sensor 14a embedded in thepower plug 14 detects the temperature of thepower plug 14 and outputs a temperature signal indicating the temperature of thepower plug 14 to thecontroller 20a provided in the chargingdevice 20. Upon receipt of the temperature signal, thecontroller 20a outputs a pilot signal corresponding to the temperature signal to thecharge control device 8 of the electrically-driven vehicle C via the chargingcoupler 16. - As described later, the pilot signal outputted from the
controller 20a has a close relationship with a charging current. Because of this, when thecharge control device 8 of the electrically-driven vehicle C receives the pilot signal indicating the charging current, thecharge control device 8 can recognize the charging current that can be supplied from thereceptacle outlet 12 via the charging cable A and conducts charging while controlling a supply current to thebattery 6 in response to the pilot signal. The electric power charged to thebattery 6 is supplied to thedrive motor 2 via the inverter 4, thus enabling the electrically-driven vehicle C to run. -
Fig. 3 depicts waveforms of pilot signals outputted from thecontroller 20a to the electrically-driven vehicle C, (a) indicating a reference waveform, (b) indicating a waveform when the temperature of thepower plug 14 is low, and (c) indicating a waveform when the temperature of thepower plug 14 is high. - Such pilot signals are further explained in detail taking a case where a commercially available 100V-power source is used and the
power plug 14 has a rated current of 15A. When the commercially available power source is 100V and the rated current of thepower plug 14 is 15A, the charging current (energization current) is set to, for example, 12A. The pilot signal indicating this charging current has the reference waveform shown inFig. 3(a) and a duty ratio (D) thereof is set to 20% (pulse width: 20%, pulse interval: 80%). - That is, the duty ratio of the pilot signal indicates the charging current itself. If the duty ratio exceeds 20%, the charging current exceeds 12A, and if the duty ratio becomes smaller than 20%, the charging current becomes smaller than 12A.
- The
power plug 14 is normally made of plastic, and assuming that the heatproof temperature thereof is 65°C, the charging cable A according to the present invention has a threshold value (for example, 50°C) set to be lower than the heatproof temperature. When the temperature of thepower plug 14 is less than the threshold value, the duty ratio is increased (D>20%) to increase the charging current, as shown inFig. 3(b) . On the other hand, when the temperature of thepower plug 14 exceeds the threshold value, the duty ratio is reduced (D<20%) to reduce the charging current, as shown inFig. 3(c) . - The duty ratio of the pilot signal and the charging current are compliant with SAE J1772 (SAE: Society of Automotive Engineers) and have, for example, the following relationship:
- Duty ratio D=20%: 12A, and
- Duty ratio D=30%: 18A.
- Further explanation is made with reference to a flowchart of
Fig. 4 indicating a charge control. At step S1 before the charging cable A is connected to the electrically-driven vehicle C, the duty ratio of the pilot signal is set to D=20%. At step S2, thepower plug 14 of the charging cable A is connected to thereceptacle outlet 12 and the chargingcoupler 16 of the charging cable A is connected to theconnector 10 of the electrically-driven vehicle C, followed by step S3, at which the temperature of thepower plug 14 is detected by thetemperature sensor 14a accommodated in thepower plug 14 and a temperature signal from thetemperature sensor 14a is inputted to thecontroller 20a of the chargingdevice 20. - At step S4, the
controller 20a compares the temperature inputted from thetemperature sensor 14a with the threshold value referred to above. - Before the
battery 6 of the electrically-driven vehicle C is charged from thereceptacle outlet 12 via the charging cable A, the temperature of thepower plug 14 is equal to an outdoor air temperature. When battery charging is initiated, the temperature of thepower plug 14 increases gradually. At step S4, if the temperature detected by thetemperature sensor 14a is less than the threshold value, the program advances to step S5, at which a control for steplessly increasing the duty ratio of the pilot signal is conducted to steplessly increase the charging current. - On the other hand, at step S4, if the temperature detected by the
temperature sensor 14a exceeds the threshold value, the program advances to step S6, at which a control for steplessly reducing the duty ratio of the pilot signal is conducted to steplessly reduce the charging current. - As described above, the duty ratio of the pilot signal has a close relationship with the charging current and if the temperature of the
power plug 14 is low, the charging current is increased. In contrast, if the temperature of thepower plug 14 is high, the charging current is reduced. This eliminates the need for the charging current to be on/off controlled, unlike the conventional way, thus making it possible to achieve a balance between a reduction in charging time and the safety of the charging cable A. - After the charging current control has been conducted at step S5 or step S6, if the
charge control device 8 of the electrically-driven vehicle C determines at step S7 that thebattery 6 of the electrically-driven vehicle C has not been completely charged, the program returns to Step S3. On the other hand, if thecharge control device 8 determines that thebattery 6 of the electrically-driven vehicle C has been completely charged, thecharge control device 8 of the electrically-driven vehicle C inputs a signal indicating completion of the charging to thecontroller 20a of the charging cable A, thereby terminating the charging of thebattery 6. - It is to be noted here that the
controller 20a sets a maximum value of the charging current (energization current) depending on the duty ratio (pulse width) of the pilot signal outputted to the electrically-driven vehicle C and that the charging current supplied to thebattery 6 of the electrically-driven vehicle C is finally determined by thecharge control device 8 of the electrically-driven vehicle C. - Although in the above embodiment the charging current has been described as being changed by changing the pulse width of the pilot signal outputted from the
controller 20a, the charging current may be changed by changing a pulse waveform (for example, a pulse amplitude (level)) other than the pulse width. - Further, although in the above embodiment the charging current has been described as being steplessly increased or reduced by steplessly increasing or reducing the duty ratio of the pilot signal, the charging current may be increased or reduced in a stepwise fashion by increasing or reducing the duty ratio of the pilot signal in a stepwise fashion.
- Also, although in the above example the charging current is steplessly increased or reduced by steplessly increasing or reducing the duty ratio of the pilot signal, the charging current may be only reduced in a stepwise fashion by reducing the duty ratio of the pilot signal in a stepwise fashion.
- In addition, although in the above example the commercially available power source has been described as being 100V, any other alternating-current voltage (for example, alternating-current 200V) can be of course used.
- A second threshold value greater than the aforementioned threshold value may be set in the
controller 20a and, in this case, if thecontroller 20a detects a temperature greater than the second threshold value, the electric circuit is blocked. -
Figs. 5 and6 depict a second example.Fig. 5 is a schematic view depicting a state where a battery of an electrically-driven vehicle is electrically charged using a charging cable according to the second example andFig. 6 is a schematic block diagram of the charging cable shown inFig. 5 . In the second example which is not part of the claimed subject matter, atemperature sensor 16a is provided in the chargingcoupler 16. Thetemperature sensor 16a detects the temperature of the chargingcoupler 16 and outputs a temperature signal indicating the temperature of the chargingcoupler 16 to thecontroller 20a of the chargingdevice 20. Upon receipt of the temperature signal, thecontroller 20a outputs a pilot signal corresponding to the temperature signal to thecharge control device 8 of the electrically-driven vehicle C via the chargingcoupler 16. Thecharge control device 8 can recognize, based on the pilot signal received, the charging current that can be supplied from thereceptacle outlet 12 via the charging cable A and conducts charging while controlling a supply current to thebattery 6 in response to the pilot signal. - This configuration can produce similar effects as in the first embodiment referred to above if abnormal heat generation occurs due to incomplete connection or arc tracking between the charging
coupler 16 and theconnector 10 of the electrically-driven vehicle C. -
Fig. 7 is a schematic block diagram of a charging cable according to a third example which is not part of the claimed subject matter, in which atemperature sensor 20b is provided in thecontroller 20a of the chargingdevice 20. It is assumed that the charging of the electrically-driven vehicle C is conducted under various circumstances and that thecontroller 20a abnormally generates heat, for example, with the chargingdevice 20 left in the hot sun. It is also assumed that abnormal heat generation may occur due to incomplete connection or arc tracking at, for example, connecting portions between the connectingcable 18 of thecontroller 20a and terminals. In the third example, thetemperature sensor 20a provided in thecontroller 20 can prevent abnormal heat generation in thecontroller 20a, thus making it possible to produce similar effects as in the above-described first embodiment. -
Fig. 8 depicts a schematic block diagram of a charging cable according to an embodiment of the present invention, in which afirst temperature sensor 14a is provided in thepower plug 14 and asecond temperature sensor 20b is provided in thecontroller 20a. It is assumed that a user may handle thepower plug 14 and the chargingcoupler 16 in a rough way. Because of this, if thetemperature sensor 14a is provided in thepower plug 14 or the chargingcoupler 16, it is conceivable that the temperature sensor deteriorates in durability. In the configuration according to this embodiment, thecontroller 20a compares a value of thefirst temperature sensor 14a provided in thepower plug 14 and that of thesecond temperature sensor 20b provided in the chargingdevice 20 with each other to thereby easily detect disconnection of thetemperature sensor 14a provided in thepower plug 14. - If the second temperature sensor is provided in the charging
coupler 16, similar effects can be obtained. Also, the chargingplug 14, the chargingcoupler 16 and the chargingdevice 20 may be provided with respective temperature sensors. - Any combination of the various embodiments referred to above can produce respective effects.
- Although the present invention has been fully described by way of preferred embodiments with reference to the accompanying drawings, it is to be noted here that various changes and modifications will be apparent to those skilled in the art. Therefore, unless such changes and modifications otherwise depart from the scope of the present invention as set forth in the appended claims, they should be construed as being included therein.
- Because the charging cable according to the present invention can reduce the charging time and enhance the durability of, for example, relays and the reliability of the equipment, it is effectively utilized as a cable for charging a drive battery of a vehicle that runs with at least the drive battery installed.
